PROBLEM TO BE SOLVED: To provide a deglutition movement measurement device capable of measuring a subject's deglutition movement without obstructing the subject's deglutition movement.SOLUTION: A deglutition movement measurement device, a device for measuring deglutition movement on the basis of a larynx's movement caused at the time of deglutition of a bolus, comprises: an electrostatic capacitance type sensor to be brought into contact with a body surface of a subject's larynx； and a measuring instrument for measuring a variation in electrostatic capacitance in the electrostatic capacitance type sensor. The electrostatic capacitance type sensor includes: a sheet-like dielectric layer； and a first electrode layer and second electrode layer that are formed on the dielectric layer's front face and rear face, respectively, so that at least parts of the electrode layers face each other while holding the dielectric layer. The electrostatic capacitance type sensor includes a sensor body that takes the first and second electrode layers' parts facing each other as a detection unit, the sensor body being reversibly deformed so that area of the front and rear faces of the dielectric layer varies.SELECTED DRAWING: Figure 2【課題】 被験者の嚥下運動を阻害することなく、被験者の嚥下運動を計測することができる嚥下運動計測装置を提供する。【解決手段】 食塊の嚥下時に生じる喉頭の運動に基づいて嚥下運動を計測する装置であって、被験者の喉頭部の体表に接触させる静電容量型センサと、前記静電容量型センサにおける静電容量の変化を計測する計測器とを備え、前記静電容量型センサはシート状の誘電層と、前記誘電層のおもて面及び裏面のそれぞれに前記誘電層を挟んで少なくとも一部が対向するように形成された第１電極層及び第２電極層とを有し、前記第１電極層と前記第２電極層との対向する部分を検出部とし、前記誘電層の表裏面の面積が変化するように可逆的に変形するセンサ本体を含む嚥下運動計測装置。【選択図】 図２
